GRAIN-STOOKERE Specification of Letters Patent. Patented Sgpt; 25, 1917;

Application filed June 2, 1916. Serial No. 101,424.

To all whom iii-may concern:

Be it known that I, \VILLIAM HAGKLY CHURCH, a subject of the KingOfGrIGEIt Britain, and resident of Superb,in the Province ofSaskatchewan, Dominion of Canada, have invented certain new and usefulImprovements in Grain-Stookers, of whiclr the following is thespecification.

This invention relates to improvements in grainstookers and the objectsof the invention are to facilitatein forming the sheaves of grain into astook and readily discharge the same, to permit of the heads of thesheaves being readily bunched together dare ing the operation ofdumpingthe stooks, to readily pack 1 the sheaves in position, and otherobjects to be made clearhereafter,and it consists essentially of theimproved construction particularly described and set forth in thefollowing specification and accom-.

panying drawings forming-part of the same.

In the drawings,

Figure 1 is an end elevation of the improved machine.

Fig.2 is a plan view of the same: i v

Fig. 3 is a side view of the machine showing the location of the packingarms and the means for operating the same.

Fig. i is an enlarged perspective view, partly in section, of thepacking arms and showing the means for preventing the sheaves beingdelivered to the basket collector when the stook isbeing clumped.-

Fig. 5 is a side elevation of the machine;

Fig. 6 is a longitudinalsection of the spring controlled drumcontrolling the actionof the upper portion of the basket collector.

Fig. 7 is a fragmentary elevation, part being in section, of the cammember and its 'coactingroller controlling the closing of the upperportion of the basketcollector.

Fig. 8 is a perspectlve View of a chain tightener adapted to coact withthe zmain drive of the machine.

Fig/9 is a fragmentary perspective view. of the mechanism controllingthe rotary 1110- tion of the basket collector.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents frame E rotatably supporting theinner end thereon, the inner' end of which is SUbSlZflll i tiallycurvilinear as shown at 17 and adaptedto engage with the pin 18 therebylimiting=the outward motion of the said lever whichis adapted to bepressed inwardly to engage :with the spokes of the wheel 1 1- in amanner to be made clear hereafter.

Rotary motion is transmitted to the shaft 11 by the disk 10 providedwith the curvilinear slot 19 having a plurality of notcl ies 20 thereinadapted to engage with the offset end of the lever 21, the other endofwhich is engaged with one ofthe orifices 22 provided in the crank arm23 of the spindle ii, the opposite end of which isprovided with acrankarm 25 angularlymlisposed to the crank arm 23 and carrying a cammember 26 adjustably mounted. thereon.

The lever 16 is provided with a projection 27 designedto be engagedbythe spring adapted to hold the said lever normally disengaged, from thespokes of the wheel. 14-, the said lever being adapted to be moved intoengagement with i the said spokes through the medium of the bell crank29 bracket 34 and is provided with a sprin 35 located between thebellcrank 29 and the said bracket.

During the forward motion of the wheel 14 rotary motion is transmittedto the shaft 11, which through the medium of the chain 36 operativelyconnecting the sprockets 37 and 37 rotates the shaft 38 which carries a.beveled pinion 39 meshing with the beveled pinion 40 mounted on thetransversely extending shaft 41 so transmitting rotating motion thereto.

This shaft 41 is rotatably mounted in the bearings 42 carried by theframe E and is provided intermediate of its length with sprockets 43operatively connected by the chains 44 to the sprockets 45 carried bythe shaft 46 rotatably mounted in one of the arms of the invertedY-shaped end brackets 48 of'the frame G, the said shaft being providedintermediate of its length with crank members 49 on which the packingarms 50 are pivotally mounted.

' The forward ends of the packing arms 50 are substantially V-shapedwhile the rear end is pivotally connected to the lower end of the links51, the upper ends of which are pivotally connected to a U-shapedbracket52 carried by the frame E.

The upper ends of the inverted Y-shaped brackets 48 are pivotallymounted on the shaft 41 and are operatively connected by an invertedU-shaped rod 53 forming part of the frame G, while the third arm of thesaid brackets is connected by a transversely eX- tending rod 54 carryinga spring 54 adapted to hold the frame G in a normal retracted position.The outer end of the crank shaft 46 makes engagement with the loweroffset end 55 of the lever 56 which is pivotally mounted to the frame Eand provided with an offset arm 57 adapted to engage with the angularstop member 58 rigidly mounted on the lower portion 13 of the basketcollector F.

The Y-shaped brackets 48 are also operatively connected by flexiblemembers 59 with the bar 60 which is provided intermediate of its lengthwith upwardly extending arms 61 slidably mounted in the invertedV-shaped frame 62, the inner face of which is adapted to guide thesheaves into the basket collector F, the flexible members 59 beingdesigned to engage intermediate of their length with the guide pulleys63 suitably secured to the frame E.

The upper portion 64 of the basket collector F is hinged to the lowerportion 13, the motion of the upper portion being controlled by thecurvilinear arms 65 rigidly secured to the curvilinear portion 12 of theshaft 11'. This upper portion 64 carries a pair of brackets 67 rigidlyattached thereto and operatively supports the drum 66, the rotation ofwhich is controlled by the spiral spring 68 wound around the pin 69having one end rigidly attached to one of the brackets 67 and the otherend extending through the periphery of the said drum.

The drum is also provided with a pair of projections 70 to which theends of the flexible members 71 are connected, the said flexible membersengaging with guide pul- Located adjacent to the curvilinear arm 65 is aresilient packing member 74 .formed in a substantially U-shaped portionwhich projects into the basket collector F, the free ends of the saidmember being rigidly connected to the upper portion 64 of the basketcollector. The upper portion 64 of the basket collector is furtherprovided with a bracket 75 carrying a roller 76 on the upper end thereofadapted to coactwith the cam portion 26 which is provided with acurvilinear slot 77 with which the-adjusting bolt 78 carried by thecrank arm 25 is adapted to engage.

Coacting with the lever 16 is a frame 7 9 which is almost completelycircular, being provided however with a gap portion which permits of thesaid lever beingfreed from engagement with the spokes, the said framebeing adapted to engage with the lever 16 and holdthe same in engagementwith the spokes until the wheel 14 has rotated through one revolutionwhen the offset end 80 of the frame allows the lever to be released andreturned under the action of the spring 28 to its normally disengagedposition;

During the period when the lever 16 is in engagement with the wheel 14,rotary motion is transmitted to the shaft 11, the inner end of which isprovided with a cam member 81 designed to engage with the roller 82carried by the offset arm 83 mounted on the U-shaped rod 53 which rodis, due to the displacement of the offset lever 56, thrown inwardlypermitting the engagement of the roller 82 and cam 81 to take place.

Simultaneously with this rotation, it is desirable that thesheavesshould not be fed to the basket collector'F, and to this end alever 84 is pivotally-mounted on an angle bracket 85 carried by theframe G, the inner end of the lever being bifurcated to embrace theU-shaped rod 53, the outer end being provided with a pinion 86 adaptedto mesh with the pinion 87 carried by the shaft 41 and the pinion 88carried 'bythe conveyer roller 89 thereby resulting in the conveyer Hbeing rendered inoperative.

This conveyer may be of any usual construction and is carried by theframe 90 Pivotally mounted to the HD1 T0116! lower end of the links 92,theupper ends of which are pivotally connected to the brackets 93carried by the frame E, the adjustment of this frame I being controlledby a lever 94 pivotally mounted intermediate of its length to oneof thebrackets 93 and pivotallv connected at its lower end to the said frame,the lever being providedwith a detent 95 coacting with the quadrant 96rigidly. mounted on the bracket 93.

marinas The adjustable frame I is pivotally con nected to one endof thelink 0 which is attached to the binder frame, audit will readily beseenthat bv utilizing a pivotal attachment of this nature thebinder may beraised or lowered to suit the length of grain being out, while the saidframe mav be adjusted to correspond with the elevation of the binder.

Simultaneously with the rotation of the basketcollector F the door Jwhich closes the end of the said basketis designed to be withdrawn fromcontact therewith under the action of gravity, andtothis end the door isattached to the frame 97 hung from the frame E. r i i The door isnormally held in closed position by the roller 98 carried by the crankarm 99 of thespindle 100, the other end of which is provided with acrank arm 101 having a plura' lity of orifices therethrough with whichone end of the link 102 engages, the'other end of the link beingadjustably connected to the lever 21 whichis operatively connected tothe spring 103 anchored to the frame E. V i

The assembly of the machine will be readily understood from theforegoing description. i i When the machine is in use the sheaves aredelivered from the binder deck I) and delivered to the frame E wherethey are engaged by the conveyer H and delivered to the basket collectorF, the upper portionv 6d of which is normally held in an open positionas will be seen by reference to Fig. 1.

i In the forwardmotion of the machine it will be understood that thesprocket wheel 37 which is rigidly attached to thewheel l-i is rotatedthereby and rotary motion is tral'ismitted through the chain drive 36 tothe shaft 38 which in turn i rotates the shaft ll causing the packingarms 50 to be reciprocated through the bottom portion 13 of the basketcollector so that as the sheaves are delivered to the basket collector Fthey are tightly packed in position by means of the said arms. hen thedesired number of sheaves have been delivered to the basket collector Fthe driver exerts a pull on the flexible member 32 thereby rotating thebell crank 31 and causing the bell crank 29 to throw the angle lever 16into engagement with the spokes of the wheel 14 so that during therotation of the wheel 14 the shaft 11 will be rotated in a forwarddirection dumping the sheaves in the basket collector on the ground inthe form of a stock.

Duriin the rotation of the shaft 11 it will be understood that the lever21 through the medium of the link 102 actuates the spindle 100 anddisengages the roller 98 from the door J permitting the same under theaction of gravity to become disengaged.

from the lower end of the basket collectm! l5" and at the same time thelever Ll. also actuates the spindle 2i causing the cam member26 toengage with the roller 00 and so close the upper portion (it on thelower portion 13 of the basketcollector.

During. the period of dumping, the resilient ll-shaped member 74 engageswith the heads of the sheaves, bimching the same together while thestook is beingdeposited on the ground so that the base of the stock willbe extended and the heads will lie close together.

When the basket collector being thus located the angle slop memberSengages with the upper offset arm 5? of the lever 50, the lower end ofwhich moves or swings the frame G aboutthe shaft 11 so that as the lowerend of the frame moves outwardly, the rod carried by theupper end of theframe moves inwardly toward the inverted vi-shaped frame This movementof the rod 53, due to its engagement with the bifurcated end of thelever 8 1, moves or retates the said lever which isfulcrumcdintel-mediate of its length to the bracketSfi so thatas thelonger arm of the lever is moved toward the inverted V-shaped frame 62the shorter arm is moved. outwardly and disengages the pinion from thepiniens 87 and 88 so rendering the conveyer H inoperative.

Simultaneously with the throwing of the pinion 86 out of gear the bar 60is operated due to the motion of the frame G, and re sults in theelevating oft-he arms ()1 which project above the frame 62 and preventany sheaves from being inadvertently delivered to the basket collectorF. During the ref tion of the basket collector F the frame (lis held inthis displaced position by the cam 81 which engages with the roller-82carried by the arm attached to the ll-shaped bar .53 forming a portionof the said frame and after the basket has completed one singlerevolution the roller 82 becomes disengaged from the cam 81 permittingthe frame G to return to its normal position in which the lever Se isactuated and the pinion 86 thrown into gear with the pinions 87 and 88resulting in the operation of the conveyor H which delivers the sheavesto the basket collector F.

The shaft fl is rotated from the main drive of the machine as alreadydescribed and the packing arms 50 tightly pack the sheaves in positionin the basket collector which when a sufficient number of sheaves havebeen delivered thereto, is again dumped in the manner already described.
